Demo-state fixture content for the `dft-komplett-demo` project (intentional Norwegian persona) and regex alternations that match Norwegian-language report markdown (`/^high\|^høy/`, `/resolution\|løsning/`) were preserved. No scanner, hook, or behavior changes — purely surface text. | | **7.7.1** | 2026-05-18 | **Playground UX strip.** Operator feedback immediately after v7.7.0: the home surface led with three project tracks (Re-onboard / New project / Command catalog) even though the catalog was the important entry point. Minimum strip delivered as three atomic commits (`b732eee` + `2a6f73f` + `81b7beb`): (1) the router always forces `activeSurface = 'catalog'` (the onboarding/home/project render functions are preserved in source but no longer routable); (2) the topbar `Home` and `Re-onboard` buttons removed, `Catalog` retained; (3) the breadcrumb org-name (`shared.organization.name` from demo state) replaced with a static `llm-security` neutral scope anchor. Fix: the hardcoded `'Plugin v7.6.1'` on line 6933 of `renderHome` (template literal not caught by the v7.7.0 grep) was synced. The onboarding concept is documented as a v7.8.0 candidate (per-command context injection) in `ROADMAP.md`.

The target alternation ended in a shared `\b`, and a word boundary cannot hold after `/` or `~` at end-of-command. Measured against the shipped pattern: bare `/` target NOT blocked `$HOME` target blocked bare `~` target NOT blocked `/usr` target blocked `/*` glob target NOT blocked swapped flags (-fr) NOT blocked sudo-prefixed NOT blocked Only targets whose first character is a word character ever satisfied the assertion, so the rule caught `/etc` but not bare root. These fell through to WARN (exit 0) — advisory only, command executed. - Pattern: `\b` moved onto the `$HOME` alternative alone, where it is meaningful (it ends in a word char, so `$HOMEDIR` is still not swallowed). Dropped from `/` and `~`. Nothing else changes: `/etc`, `/home`, `./build` behave exactly as before. - The old test file encoded this defect as expected behaviour, with a NOTE claiming the pattern "requires separate flag groups (e.g. -f -r, not -rf combined)". That diagnosis was wrong — the `/etc` case blocks fine with merged flags. Comment replaced with the real root cause. npm test: 1872/1872 green (1865 + 7 new).

The resulting TypeError propagated out of scanOneExtension into mapConcurrent, which awaited fn() with no per-item try/catch, so Promise.all rejected and the ENTIRE ide-scan aborted. One malformed plugin directory on disk was enough to take down the scan of every other installed extension — including, in an audit context, a plugin that is malformed precisely because it is hostile. - scanOneExtension: guard is now `!parsed || !parsed.manifest`, and the parser's own warnings are carried into the result so the reason for the skip survives instead of being replaced by a generic message. - unscannableExtension(): the result envelope is extracted so the early return and the isolation belt below produce the same shape. - Belt (defense-in-depth): the scanOneExtension call site catches per extension and yields an unscannable result. mapConcurrent stays generic — the isolation lives at the call site, not in the helper.

charset=UTF-8 Content-Transfer-Encoding: 8bit stripInjection is the remote-scan indirection layer: its `sanitized` output is what an LLM agent actually reads, verbatim, via sanitized_content in the evidence package. It scanned two variants of each file — the raw text and normalizeForScan(text) — but removed matches with `sanitized.replace(match[0], ...)` against the RAW text only. For a match found in the decoded variant, match[0] IS the decoded string, which by construction does not occur in the raw text. The replace was therefore a silent no-op: the finding was reported while the encoded payload was passed to the agent untouched. Every obfuscation the normalizer exists to defeat — HTML entities, URL encoding, \u escapes, hex, base64, letter-spacing, Unicode tags — reached the agent intact. The worst case is the intended one: detection said "critical injection found" and shipped the injection along with the verdict. - Pass 1 redacts the whole source LINE whose own normalized form carries the pattern. Line granularity is deliberate: decoding is not length-preserving, so decoded match offsets cannot be mapped back onto the original text. - Pass 2 keeps the existing literal replacement and finding collection. - Residual gap, made explicit rather than silent: a payload encoded across MULTIPLE lines matches whole-text normalization but no single line, so it cannot be attributed. Those findings now carry `unstripped: true`. Whole-file redaction was considered and rejected — normalizeForScan base64-decodes any long blob, so a benign asset could blank an entire file's evidence. - stripInjection exported via __testing, and main() is now behind the standard isMain guard (copied from dashboard-aggregator.mjs) so importing the module does not execute the CLI. CLI verified unchanged against the evil-project-health fixture: 7 files, 6 injection findings, risk_level critical. This boundary had no direct test coverage before this commit. npm test: 1890/1890 green (1884 + 6 new).

Correction to the review's framing: this does NOT break parsePluginXml's no-throw contract. The per-field safe() wrapper catches it. The actual defect is quieter — the affected field is discarded and replaced with '', with only a warning. A plugin whose carries one out-of-range reference parses as name: "" while pluginId and every other field survive, so name-based checks (JetBrains typosquat detection against the top-plugin list) run against an empty string. Severity is below the HIGH it was filed as: a document containing a code point above 0x10FFFF is not well-formed XML, so IntelliJ would reject such a plugin too — the evasion yields a plugin that does not load. The fix is still correct and one line of logic. - isDecodableCodePoint(): integer, >= 0, <= 0x10FFFF. - Undecodable references are now left literal, matching how lenient parsers treat unrecognised entities and how this same function already treats unknown named entities. Regression test drives parsePluginXml with hex and decimal references just past and far past the maximum, asserts the no-throw contract still holds, and pins that valid references, the maximum valid code point, and named entities still decode. npm test: 1901/1901 green (1890 + 11 new).

Both sinks in `scanners/auto-cleaner.mjs` are now - `spawnSync` argv-arrays; `execSync` is no longer imported there. -- Regression coverage is deliberately TWO tests (`tests/scanners/auto-cleaner-rce.test.mjs`): the belt - in `applyFixes` (metachar refusal) stops hostile input BEFORE the sink, so a single applyFixes-level - test would pass without proving the shell was gone. `validateContent` is exported for that reason — - do not "tidy" that export away. +- Test-pollution trap (hit and fixed): `jetbrains-parser.test.mjs` asserts globally that no + `llmsec-jb-*` dir survives in tmpdir.
